Which of the following types of contracts is created through the behavior of the parties involved?

A contract created through the behavior of the parties involved is known as an implied contract. This type of contract arises not from an explicit agreement but rather from the actions, conduct, or circumstances of the parties. For instance, when a person goes to a restaurant and orders a meal, an implied contract is formed that they will pay for the food, even though no formal agreement was signed.

Implied contracts rely on the inferred intentions of the involved parties based on their behavior or the context of their interactions. This contrasts with express contracts, where the terms are clearly articulated either orally or in writing. Unilateral contracts involve a promise made by one party in exchange for the act of another, while bilateral contracts consist of mutual promises exchanged between two parties. Each of these contract types operates under different principles than an implied contract, which is specifically tied to the actions of the parties rather than explicit promises or agreements.
